RE: NEC-LIST: Imperial and metric units and the like

Harry,

1.8*10**12 should be the distance travel by light in furlongs per fortnight.

To make the unit more interesting or confusing, we know

1 kilometer = 1000 meters
1 kilometer = 4.97097 furlongs
1 furlong = 6.6 engineer's chain
1 engineer's chain = 1.51515 chain (surveyor)
1 chain (surveyor) = 4 rod, pole or perch
1 rod, pole or perch = 2.75 fathom
1 fathom = 1.8288 meter

Hence,

1 furlong = 4.97097 * 6.6 * 1.51515 * 4 *2.75 * 1.8288 meter !

Regards,
Roger Tay

Dear NEC-lister,

Any that are determined not to metricate may find the following
information useful. The velocity of light in furlongs per fortnight is
1.80*10**12. While not in widespread engineering use, this well
pedigreed imperial unit does have a certain poetic appeal.

Sincerely,
Harry E. Green
